iS Clinical products are not certified as organic, although we use organic sources whenever possible. Our ingredients are sourced from all over the world so that we may obtain the finest quality ingredients, harvested at the optimum time for desired activity. In general, iS Clinical ingredients are better than what is commonly considered to be “natural.” Many iS Clinical ingredients are bio-identical, i.e. exactly like the same molecule made in the human body. This is the very best and most natural ingredient possible. Our ingredients are pharmaceutical grade whenever possible and are the best quality available globally. Pharmaceutical grade quality assures standards of purity, potency, and effectiveness, and is the same quality of ingredients used in medications. Pharmaceutical grade ingredients are expensive but iS Clinical believes they are worth the expense in terms of end-product quality and efficacy. Using the highest quality ingredients also means that only small application amounts are needed for excellent results and a bottle will last several months.
